[Multifocal glioma. Apropos of 10 cases]

The authors report 10 cases of multifocal glioma of the brain. There are distinguished in multicentric tumors, when lesions develop independently in the space and time and multiples tumors when they are in connection by spreading process. They analyzed the factors that could permit to distinguish these gliomas. Multicentric tumors are histologically of low grade with gradual evolution, and from different histological nature and topography. In other hand, multiple gliomas are from malignant histology and develop simultaneously. The CT scan and biopsy in stereotaxic condition could permit to recognize these two parts which the prognosis is different.
